Initial DEC 21143 support from Stephan Wilms <Stephan.Wilms@CWA.de>.

Browse Source 
Comments follow:

 This support is (for now) only available for the __i386 target, because
 that's the only testing platform I have. It should to my best knowledge
 work in the same way for the "__PPC" target, but someone should test
 this first before it's put into the code. Thanks go to Andrew Klossner
 who provided the vital information about the Intel 21143 chip.

 (FWIW: my network card is a Kingston KNE100TX with 21143PD chip)
